An e-truck makes its way through the city – quietly and emission-free. Along its route, the e-vehicle collects parcels from post offices and transports them to customer delivery points. Without recharging, the environmentally friendly truck can cover a distance of at least 300 kilometers, making it highly suitable for use in urban areas. The truck with electric drive has a large battery, so the charging process takes quite some time and can have a duration of up to 9 hours. The truck is thus usually charged overnight at the depot.

The use of electric drives in heavy-duty commercial vehicles is becoming increasingly important. The statistics indicate that several thousand electric trucks are already on the road in Germany. For example, electrification is taking place in the construction industry, waste collection and postal services. And it’s no wonder, because electric trucks make it possible to transport goods more quietly and without emissions while maintaining high levels of productivity at the same time.

But the possibility of fire in the event of a faulty charging infrastructure should not be underestimated. Although battery-powered trucks help to improve the quality of life in cities and reduce CO2 emissions, safe charging is very important and it’s essential for fire prevention.

As a fire prevention measure, standards-compliant functional testing of electric vehicles, battery storage systems and the charging infrastructure should be performed. More and more emphasis is being focused on selecting the right measuring and test instruments to this end. As one of the world’s leading suppliers of measuring systems, Gossen Metrawatt also ensures enhanced safety for your e-truck fleet with rugged, innovative test technology.

Safe E-Mobility
Testing of Vehicles with Electric Drives

Are you a car manufacturer who needs to verify that electric vehicles meet international electrical safety requirements in accordance with UN ECE-R100? Can you assure that all drive components are protected against short-circuits and that no potential danger exists for passengers or service personnel working on electrical components?

High-voltage safety is becoming increasingly important for the successful operation of electric vehicles, but it’s often not taken into consideration until it’s too late. Gossen Metrawatt has developed efficient solutions for testing the effectiveness of protective measures in electric vehicles in order to ensure safe work on vehicles with HV technology. The METRAHIT IM E-DRIVE BT measuring instrument makes it possible to detect malfunctions in vehicles at an early stage and ensure effective fire protection.

Fail-Safe Power Supply
Testing of Storage Batteries

Suppose you operate large fleets of electric vehicles and you’re dependent on a continuous supply of electrical power. You make use of efficient UPS systems in your depot in order to ensure uninterrupted e-mobility, and to protect operations from power failures and voltage dips. Battery storage capacity plays a central role for UPS systems, which can decrease as the battery ages, thus compromising the quality of the power supply.

We recommend checking battery status at regular intervals in order to avoid power supply issues and to provide high-quality transportation services. Determining the storage batteries’ state of health makes it possible to identify defective blocks at an early stage, thus delaying costly replacement of UPS batteries.

With its METRACELL BT PRO, Gossen Metrawatt offers a compact, rugged instrument for testing storage batteries. The battery-powered test instrument features a wide range of test functions and provides a comprehensive picture of the battery’s condition by performing capacitance, resistance, voltage and interval measurements.

METRACELL BT PRO

Product benefits:

• Early diagnosis of possible damage to stationary battery systems
• Precise measurement of internal resistance for exact SoH evaluation
• Measurements are possible under float, charging and discharging conditions

Reliable Charging Infrastructure
Safety Testing of Charging Points and Power Quality Analysis

Performance requirements grow along with increasing numbers of vehicles in the e-vehicle fleet. Several electric vehicles must be charged at the same time. In addition to a consistently safe charging process, this also necessitates an effective load management system. Regardless of which charging technology is used – plug-in, pantograph or inductive – regular testing of electrical safety at charging stations and a comprehensive power quality analysis are necessary. Compliance with legal and normative requirements is cost-saving and economical. Investing in specialized, top-quality test instruments pays off.

Based on its expertise in the field of AC and DC power analysis, Gossen Metrawatt offers diagnostic testers for simulating the charging process. In combination with the PROFITEST MF XTRA and the PROFITEST PRIME, you can easily test and document the effectiveness of protective measures for electrical safety at AC/DC charging points. With the help of the LINAX PQ1000 power quality analyzer, you can analyze energy consumption and grid status, and detect power quality problems at an early stage. Continuous monitoring can prevent operational failures which may lead to significant financial losses. The instrument permits continuous assessment of power quality in accordance with IEC 61000-4-30 edition 3 in class S.
